Like for most devices connected to WiFi, one would expect push notifications when the bucket was full.  Customer service confirmed this is not true for this unit, which otherwise works great.  You have to access the app to see if the bucket is full.Very disappointing to spend extra $$$ when it lacks this basic capability.  I have many household devices connected by wifi and they all push notifications of when a basic action is needed or the unit is or isn't functioning correctly.
